This is an aluminum select fire Salient Arms 2011 pre-upgraded with reinforced internal components to withstand C02 and prolonged, high ROF fully automatic cycling. This monster is my go-to when I want a compact, reliable sidearm which can lay down some serious suppressive fire at literally the flick of a switch. Price is shipped w/ 1 mag via the pal of payment. Message if interested in the attachments, extra/extended mags, or want to negotiate a trade offer.
